Thanks for the report!

Substitute availability should start to improve somewhat, as we've made
some changes in the build farm that will avoid some "spurious" build
failures with aarch64. In the long run, we are hoping to acquire more
aarch64 hardware to match the growing demand.

Hm, that's a bug :/

It might help if you shared the config.scm you used for creating your vm
images.

Let's make it happen!
